How to make a sheet metal box with curved edges.
Minimise the gap setting to the least value allowed.
Rounding metal with the bevel heads from beveltools ensure a smooth and consistent rounded edge on sheet plate pipe and hole.
Make sure that it is lined up with the line you measured earlier.
Once all of the squares are cut out you ll be left with the four flaps.
Lower the clamping bar handle down to clamp your metal into place.
It is easier to cut off a 4 x 12 strip if you have a 12 x 12 sheet first then cut two 3 1 2 pieces from that strip.
Model a baseflange with the radius down to the bare minimum.
You can create the perfect uniform radius with these bevel heads.
The sides will be 3 x 3 but we add 1 2 tabs on three sides.
Use your bending leaf handles to slowly fold your sides and tabs to 90 degrees.
It s suppressed in the flat pattern.
So mark out two 4 x 3 1 2 sections of sheet metal and cut it in the metal shear.
Repeat steps 1 5 for the opposite side of your box.
Return your bending leaf to neutral position and lift up your teeth to remove your bent metal.
We start the box by making its sides.
Step 1 is to design the corners like shown in above image.
Bend the edge 90.
Now if you make the box by creating an extruded rectangle add fillets to all of the edges and corners and then shell the thing outward you can make that into a sheetmetal and add louvers and ports and stuff like that.
Create the rest of the bends with the mitre flange command.
Insert the first edge into a bending brake.
Step 2 is to tack weld the cornerfill into place.
Step 3 weld all seams.
You ll be bending over the edges of these flaps to make smooth edges for the top of the box.
This is how easy it is to make a rounded edge on metal.
